  7. What is MTR (...

What is MTR ( Mill Test Report) for material’s chemical and physical properties?

mill test report (MTR) and often also called a certified mill test report, certified material test report, mill test certificate (MTC), inspection certificate, certificate of test, or a host of other names, is a quality assurance document used in Fanovo that certifies a material’s chemical and physical properties and states a product made of metal (steel, aluminum, brass or other alloys) complies with an international standards organization (such as ANSI, ASME, etc.) specific standards.

Mill here refers to an industry which manufactures and processes raw materials.

One MTC must contain the following information: steel mill’s name, heat number, batch number, final test result, steel pipe dimension (steel pipe diameter, wall thickness, length), quantity, steel grade, standard/specification, chemical analysis composition results, mechanical test properties results. If applicable, there also should be hydro test result, UT result, hardness test result, CVN impact results, metal graphic result etc.

Usually mill will issue a table as the format of MTC of steel pipe or steel plate, to be filled with enough test results. Companies will issue a report format as MTC for steel pipes.

There are mainly two types of MTC in steel industry, as for steel plates or steel pipes, there must be specific inspection scope or lists:

  1. MTC EN 10204 3.1 :MTC 3.1 is issued by the manufacturer in which they declare that the products supplied are in compliance with the requirements of the order and in which they supply test results. This is the most common MTC in steel industry, when there is no extra requirement of customer for TPI inspection and witness of production and inspection of tests.
  2. MTC EN 10204 3.2 :MTC 3.2 refers to the report prepared by both the manufacturer’s authorized inspection representative, independent of the manufacturing department and either the purchaser’s authorized inspection representative or the inspector designated by the official regulations and in which they declare that the products supplied are in compliance with the requirements of the order and in which test results are supplied.

Fanovo engineering department will provide MTC to each customer around the world. We will ensure superior quality of all materials we use.
